Is there any bad effect on Source store when i install Connector?

No, there is not.
Connector exists for migration purpose only. It help migration app can copy, not modify, the data you’d like to move to a target store.
With each Connector we provide a unique Security Token thus only you can access your Source store database.
And once the migration is done, it is totaly safe to delete the Connector.
